Find Similar Products in a Catalog

This endpoint allows similarity comparisons on existing or new products against an existing catalog.

The input is a set of products, which can either be existing products in the catalog (item_id) or new products (items).

For each item, there is an output of how similar it is (between 0 and 1) against every product in the catalog it is being compared to. Ordering this output from highest to lowest is the equivalent of finding the most similar products in the catalog.

By default, similarity takes into account both product images and metadata.
